Abstract
Description
Technical Field
[0001] This utility model relates to the field of range hood technology, and in particular to a flipping structure for a range hood and a range hood itself. Background Technology
[0002] In modern kitchen cooking environments, range hoods are the most common smoke extraction devices. In the design of traditional range hoods, the smoke collection plate usually needs to be manually rotated by the user for opening and closing control.
[0003] However, most range hoods on the market currently have a significant problem with their smoke collection plates: they cannot stay at any angle within a certain range. This defect causes considerable inconvenience when users need to clean the range hood. For example, when cleaning the back of the flap or internal components, because the flap cannot be stably stopped at the correct angle, users need to continuously support it by hand or take other temporary fixing measures. This not only increases the difficulty of cleaning and reduces cleaning efficiency, but may even lead to safety hazards during the cleaning process. Utility Model Content
[0004] This utility model provides a flipping structure for a range hood and a range hood in which the smoke collection plate can be stopped at the angle required by the user, improving the safety and convenience of cleaning the smoke collection plate.
[0005] To solve the above problems, the present invention adopts the following technical solution:
[0006] According to a first aspect of the present invention, an embodiment of the present invention provides a flipping structure for a range hood, comprising a bracket, a connecting rod, a support rod, and two elastic damping components. The bracket includes two side plates, one end of the connecting rod is located between the two side plates, and the other end is used to connect to a smoke-collecting plate. Both ends of the support rod are respectively connected to the two side plates, and the support rod passes through the connecting rod, allowing the connecting rod to rotate relative to the support rod. The two elastic damping components are respectively disposed on both sides of the connecting rod, and each elastic damping component includes a first anti-slip plate and a second anti-slip plate sleeved on the support rod. The device includes a first anti-slip insert and two elastic damping components. Each elastic damping component comprises an integrally formed elastic part and a damping part. The elastic parts of the two elastic damping components abut against each other. The two sides of the first anti-slip insert abut against the connecting rod and the damping part of one of the elastic damping components, respectively. The two sides of the second anti-slip insert abut against the side plate and the damping part of the other elastic damping component, respectively. Damped rotation can be achieved between the first anti-slip insert and the connecting rod, between the first anti-slip insert and the damping part it abuts against, between the second anti-slip insert and the side plate, and between the second anti-slip insert and the damping part it abuts against.
[0007] In some embodiments, the elastic part is disc-shaped and protrudes outward from the center, and the elastic part is provided with a through hole; the damping part is a damping ring surrounding the outer side of the elastic part, and the surface of the damping ring is provided with damping patterns.
[0008] In some embodiments, both the first and second anti-slip mediators are annular, and anti-slip patterns are provided on both sides of the first and second anti-slip mediators. The anti-slip patterns extend radially, with the anti-slip patterns of the first anti-slip mediator extending from its inner side to its outer side, and the anti-slip patterns of the second anti-slip mediator extending from its inner side to its outer side.
[0009] In some embodiments, the support rod is a screw, and both side plates are provided with coaxial through holes. The screw passes through the through holes of the two side plates, and a nut is fitted on the screw. The heads of the nut and the screw are respectively located on the outer sides of the two side plates.
[0010] In some embodiments, an anti-slip washer is fitted onto the screw, and the anti-slip washer is disposed between the nut and the side plate; one of the side plates has a shaped hole, and the screw has a shaped portion adapted to the shaped hole, the shaped portion being disposed in the shaped hole.
[0011] In some embodiments, the bracket is provided with a limiting member for limiting the rotation angle of the connecting rod in the direction of opening the smoke-collecting plate.
[0012] In some embodiments, the two elastic damping assemblies include four elastic damping elements distributed along the axial direction of the support rod. In the direction along the axial direction of the support rod and from the connecting rod to the side plate, the two sides of the first anti-slip mediator abut against the connecting rod and the damping portion of the first elastic damping element, the elastic portion of the first elastic damping element abuts against the elastic portion of the second elastic damping element, the damping portion of the second elastic damping element abuts against the damping portion of the third elastic damping element, the elastic portion of the third elastic damping element abuts against the elastic portion of the fourth elastic damping element, and the two sides of the second anti-slip mediator abut against the side plate and the damping portion of the fourth elastic damping element, respectively.
[0013] According to a second aspect of the present invention, an embodiment of the present invention provides a range hood, including a smoke collection hood, a smoke gathering plate, and a flip-up structure of the range hood described in any of the first aspects above. The front side of the smoke collection hood is provided with a smoke inlet, the smoke gathering plate is disposed on the front side of the smoke collection hood, the bracket is fixed inside the smoke collection hood, and the connecting rod is connected to the smoke gathering plate.
[0014] In some embodiments, the front side of the smoke collection hood is provided with a magnetic element, which attracts and fixes the smoke collection plate when the smoke collection plate is rotated to the closed state.
[0015] In some embodiments, a guide plate is provided at the lower end of the smoke gathering plate. When the smoke gathering plate is rotated to the closed state, the guide plate is inserted into the smoke inlet and abuts against the two side walls of the smoke inlet.
[0016] This utility model has at least the following beneficial effects: The connecting rod of this utility model can rotate relative to the bracket, and the smoke collecting plate can rotate relative to the smoke hood accordingly. Since the first anti-slip plate and the connecting rod, the first anti-slip plate and the damping part that abuts against it, the second anti-slip plate and the side plate, and the second anti-slip plate and the damping part that abuts against it can all dampen the rotation, the smoke collecting plate will be subjected to damping force during the rotation. After the user stops rotating the smoke collecting plate, the smoke collecting plate can stay at the angle required by the user, which improves the safety and convenience of the smoke collecting plate cleaning process.
[0017] In addition, since the elastic damping component includes an integrally molded elastic part and a damping part, there is no need to configure additional elastic devices, which simplifies the structural configuration. Attached Figure Description

[0035] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0036] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0037] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0038] An embodiment of this utility model provides a flipping structure for a range hood, such as... Figure 1 , Figure 2 and Figure 4As shown, the device includes a bracket 100, a connecting rod 200, a support rod 300, and two elastic damping components 400. The bracket 100 includes two side plates 110, which are parallel to each other and spaced at a predetermined distance. One end of the connecting rod 200 is located between the two side plates 110, and the other end is used to connect to the smoke-collecting plate. Both ends of the support rod 300 are connected to the two side plates 110 respectively, and the support rod 300 passes through the connecting rod 200. The connecting rod 200 is provided with a rotating hole for the support rod 300 to pass through, allowing the connecting rod 200 to rotate relative to the support rod 300. When the connecting rod 200 rotates, it can correspondingly drive the smoke-collecting plate to rotate.
[0039] Two elastic damping components 400 are respectively disposed on both sides of the connecting rod 200, and each elastic damping component 400 includes a first anti-slip medium, a second anti-slip medium, and two elastic damping elements sleeved on the support rod 300. Each elastic damping element includes an integrally formed elastic part 401 and a damping part 402. The elastic part 401 can elastically deform. The elastic parts 401 of the two elastic damping elements abut against each other. The two sides of the first anti-slip medium abut against the connecting rod 200 and the damping part 402 of one of the elastic damping elements, respectively. The two sides of the second anti-slip medium abut against the side plate 110 and the damping part 402 of the other elastic damping element, respectively. Damped rotation can be achieved between the first anti-slip mediator and the connecting rod 200, between the first anti-slip mediator and the damping part 402 that abuts against it, between the second anti-slip mediator and the side plate 110, and between the second anti-slip mediator and the damping part 402 that abuts against it. This will generate a damping force on the rotation of the connecting rod 200, limiting the rotation of the connecting rod 200 under the action of gravity.
[0040] When using the range hood, users can manually rotate the smoke collection plate to the desired angle. After the force applied by the user is removed, the connecting rod 200 will remain at the angle rotated by the user under the action of damping force, and the smoke collection plate can stay at the desired angle accordingly. Users can free their hands to clean the smoke collection plate, which improves the safety and convenience of the smoke collection plate cleaning process.
[0041] Meanwhile, since the elastic damping component includes an integrally formed elastic part 401 and damping part 402, there is no need to configure additional elastic devices, which can simplify the structural configuration and strengthen the connection between the elastic part 401 and the damping part 402.
[0042] In some embodiments, such as Figure 2-4As shown, the two elastic damping assemblies 400 include four elastic damping elements distributed along the axial direction of the support rod 300. For ease of explanation, in the direction along the axial direction of the support rod 300 and from the connecting rod 200 to the side plate 110, the four elastic damping elements are respectively the first elastic damping element 431, the second elastic damping element 432, the third elastic damping element 433, and the fourth elastic damping element 434. The two sides of the first anti-slip plate 410 respectively abut against the connecting rod 200 and the first elastic damping element 434. The damping portion 402 of the first elastic damping member 431 abuts against the elastic portion 401 of the second elastic damping member 432, the damping portion 402 of the second elastic damping member 432 abuts against the damping portion 402 of the third elastic damping member 433, and the elastic portion 401 of the third elastic damping member 433 abuts against the elastic portion 401 of the fourth elastic damping member 434. The two sides of the second anti-slip plate 420 abut against the side plate 110 and the damping portion 402 of the fourth elastic damping member 434, respectively. Rotation is also damped between the damping portions 402 of the second elastic damping member 432 and the damping portions 402 of the third elastic damping member 433.
[0043] In this embodiment, by adding two elastic damping elements to the elastic damping assembly 400, the length of the elastic damping element 400 can be extended to accommodate the distance between the connecting rod 200 and the side plate 110, and the damping force is also increased accordingly, further restricting the rotation of the connecting rod 200 under the action of gravity. Of course, more elastic damping elements can be configured according to actual needs.
[0044] In some other embodiments, two first anti-slip mediators 410 may be provided, one side of which abuts against the connecting rod 200, the other side of which abuts against one side of the other first anti-slip mediator 410, and the other side of the other first anti-slip mediator 410 abuts against the damping part 402 of the elastic damping member.
[0045] Two second anti-slip mediators 420 can be provided. One side of one second anti-slip mediator 420 abuts against the side plate 110, the other side of one second anti-slip mediator 420 abuts against one side of another second anti-slip mediator 420, and the other side of the other second anti-slip mediator 420 abuts against the damping part 402 of the elastic damping member.
[0046] In some embodiments, such as Figure 3-5 As shown, the elastic part 401 is disc-shaped and protrudes outward from the center. The elastic part 401 is provided with a through hole 403, through which the support rod 300 passes. The damping part 402 is a damping ring surrounding the outer side of the elastic part 401, and the surface of the damping ring is provided with damping patterns 403.
[0047] The protruding portion of the elastic part 401 can be concave under external force, and can elastically return to its original position after concavity, thereby enabling the elastic part 401 to elastically deform. The protruding portion of the elastic part 401 can protrude outward in an arc shape.
[0048] The damping groove 403 increases the friction of the contact surface, thereby providing damping force. The damping groove 403 can extend radially along the damping ring.
[0049] In some embodiments, such as Figure 3 and Figure 6 As shown, both the first anti-slip mediator 410 and the second anti-slip mediator 420 are annular, and both sides of the first anti-slip mediator 410 and the second anti-slip mediator 420 are provided with anti-slip textures 411. The anti-slip textures 411 extend radially. The anti-slip textures 411 of the first anti-slip mediator 410 extend from its inner side to its outer side, and the anti-slip textures 411 of the second anti-slip mediator 420 extend from its inner side to its outer side.
[0050] The anti-slip texture 411 can also increase the friction of the contact surface, thereby providing damping force. In this embodiment, the anti-slip texture 411 extends from the inner side of the anti-slip substrate to the outer side, and the longer texture can provide greater friction.
[0051] In some embodiments, such as Figure 3 As shown, the support rod 300 is a screw, and both side plates 110 are provided with coaxial through holes 111. The screw passes through the through holes 111 of the two side plates 110, and a nut 310 is fitted onto the screw. The heads of the nut 310 and the screw are located on the outer sides of the two side plates 110, respectively. By tightening the nut 310, the heads of the nut 310 and the screw clamp the two side plates 110, thereby securing the support rod 300 to the two side plates 110.
[0052] Meanwhile, the use of screws and nuts for mounting facilitates the assembly and disassembly of the elastic damping assembly 400.
[0053] In some embodiments, such as Figure 3 and Figure 7 As shown, an anti-slip washer 320 is fitted onto the screw. The anti-slip washer 320 is placed between the nut 310 and the side plate 110. The anti-slip washer 320 increases the friction and restricts the screw from rotating relative to the side plate 110.
[0054] The anti-slip washer 320 has multiple recesses 321 along its circumference, which makes the anti-slip washer 320 form a wave-like structure along its circumference. The surface of the anti-slip washer 320 will be uneven, which can further increase the friction and limit the rotation of the screw relative to the side plate 110.
[0055] In some embodiments, such as Figure 3As shown, one of the side plates 110 has a perforation 111, and the screw has a shaped portion 330 that matches the shaped hole. The shaped portion 330 passes through the shaped hole 111, and the cooperation between the shaped portion 330 and the shaped hole 111 restricts the screw from rotating relative to the side plate 110, thereby improving the stability of the support rod 300 fixed to the side plate 110.
[0056] In some embodiments, such as Figure 3 As shown, the bracket 100 is provided with a limiting member 500 to limit the rotation angle of the connecting rod 200 in the direction of opening the smoke-collecting plate. This can prevent the connecting rod 200 from rotating too much in the direction of opening the smoke-collecting plate, and ensure that the damping force generated by the elastic damping component is sufficient to support the connecting rod 200 and the smoke-collecting plate.
[0057] When the connecting rod 200 rotates towards the direction of opening the smoke-collecting plate until it abuts against the limiting member 500, the limiting member 500 can restrict the connecting rod 200 from rotating further. The limiting member 500 can be a screw, which can pass through the two side plates 110 and be locked and fixed to the side plates 110 by a matching nut.
[0058] An embodiment of this utility model provides a range hood, such as... Figure 8 and Figure 9 As shown, the range hood includes a smoke collection hood 600, a smoke gathering plate 700, and a flip-up structure of any of the above embodiments. For a detailed description of the flip-up structure of the range hood, please refer to the above embodiments, which will not be repeated here. The front side of the smoke collection hood 600 is provided with a smoke inlet 610, through which cooking fumes can enter the interior of the smoke collection hood 600. The smoke gathering plate 700 is disposed on the front side of the smoke collection hood 600, with a bracket fixed inside the smoke collection hood 600, and a connecting rod 200 connected to the smoke gathering plate 700.
[0059] When the connecting rod 200 rotates relative to the bracket, the smoke collecting plate 700 also rotates accordingly. The smoke collecting plate 700 can rotate to an open state and a closed state. When the smoke collecting plate 700 is in the closed state, it can completely cover the smoke inlet 610, or, as shown in 8, only cover a part of the smoke inlet 610, which is equivalent to reducing the air intake area. When the smoke collecting plate 700 is in the open state, as shown in 9, the smoke inlet 610 is fully open, the air intake area is larger, and more oil fumes can be quickly drawn in.
[0060] When using the range hood, users can manually rotate the smoke collection plate 700 to the desired angle. After the force applied by the user is removed, the connecting rod 200 will remain at the angle rotated by the user under the action of damping force, and the smoke collection plate 700 can stay at the desired angle accordingly. Users can clean the smoke collection plate 700 by freeing their hands, which improves the safety and convenience of the cleaning process.
[0061] In some embodiments, such as Figure 9 As shown, a magnetic component 620 is provided on the front side of the smoke collection hood 600. When the smoke collection plate 700 is rotated to the closed state, the magnetic component 620 attracts and fixes the smoke collection plate 700, and the smoke collection plate 700 can remain stable in the closed state. When the user opens the smoke collection plate 700, only a little force is needed to separate the smoke collection plate 700 from the magnetic component 620, making it easier for the user to open the smoke collection plate 700.
[0062] In some embodiments, such as 8 and Figure 9 As shown, a guide plate 710 is provided at the lower end of the smoke collection plate 700. When the smoke collection plate 700 is rotated to the closed state, the guide plate 710 is inserted into the smoke inlet 610 and abuts against the two side walls of the smoke inlet 610. This can restrict the smoke collection plate 700 from moving to both sides of the smoke collection hood 600, reduce the abnormal movement of the smoke collection plate 700 during the operation of the range hood, and keep the smoke collection plate 700 stable in the closed state.
[0063] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
